Early Experience in Starting a Laparoscopic Liver Resection Program in Greece

Is Single-Incision Laparoscopic Liver Surgery Safe and Efficient for the Treatment of Malignant Hepatic Tumors? A Systematic Review

PURPOSE

The objective of this review was to evaluate the safety and efficiency of single-incision laparoscopic liver surgery (SILLS) for malignant liver lesions.

METHODS

A retrospective review of the Medline database was performed, including studies published up to February 2019.

RESULTS

Overall, 69 patients (50 males) with a median age of 61 years (range, 31-90) from 16 studies underwent SILLS for malignant liver disease and were included in this review. The majority of patients underwent resection for hepatocellular carcinoma (n = 52, 75 %), followed by metastatic disease (n = 15, 22 %). The hepatic lesions were located in anterolateral liver segments in 62 patients (90 %) and in posterosuperior liver segments in 7 patients (10 %). Sixty-five patients (94 %) underwent minor liver resection. The median blood loss was 200 mL (range 0-2500), while 4 patients that underwent single-port resection were converted to either conventional laparoscopy or open resections. Two cases were reported to be associated with postoperative complications in the single-port group (1 [1.7 %] grade Dindo-Clavien I-II, 1 [1.7 %] grade Dindo-Clavien III-IV), while no complications were noted in the multiport group. All patients successfully underwent R0 resection.

CONCLUSIONS

SILLS seems to be a safe and efficient treatment modality for malignant liver disease when performed by experienced surgeons in carefully selected patients. More studies are needed to better identify which patients may benefit from such an operative approach.

Safety and Efficacy of Laparoscopic Liver Resection for Lesions Located on Posterosuperior Segments: A Meta-Analysis of Short-term Outcomes

INTRODUCTION

Laparoscopic liver resections (LLR) are currently acknowledged as safe and efficient procedures. LLR in posterosuperior (PS) segments are considered highly challenging procedures. The aim of our meta-analysis was to evaluate the effect of LLR versus open liver resection on short-term outcomes for PS segment lesions.

MATERIALS AND METHODS

A systematic search of Medline, Scopus, Google Scholar, Cochrane CENTRAL Register of Controlled Trials and Clinicaltrials.gov databases for articles was performed.

RESULTS

Five studies involving 531 patients who underwent resection for PS liver segments lesions were included. LLR were associated with reduced blood loss and overall complications. Operative time, blood transfusion, R0 resection, resection margin, hospital stay, and mortality were not found different among the 2 groups.

CONCLUSIONS

Notwithstanding their highly demanding nature, LLR in PS segments are safe and efficient procedures in the hands of experienced surgeons. Further studies are mandatory to evaluate their effect in these challenging liver resections.
